Hi Lorraine,
I have enjoyed reading your essay.There are lots of passages I could talk about. here's one. You wrote. "It is necessary that "the universe" apprehends itself from within i.e. from a subjective viewpoint from within. So there exists no external-to-the-universe objective-viewpoint information; and there is also no internal-to-the-universe objective-viewpoint information about reality, though in practice a symbolic (i.e. written or spoken) representation of subjective viewpoints that have collective agreement and scientific confirmation is labelled "objective". The ordinary reality of chairs and trees and people and animals is also agreed objective reality, although this information is always subjectively apprehended."
It is necessary that components of the universe with awareness apprehend it subjectively (from within) but is it necessary for the universe as a whole to have subjective self awareness? I think it can be all that it is without that self awareness co-existing. A source object exists from which information can be transmitted potentially giving all possible viewpoints even if they are not produced, eg. no light, no observers. In "Shut up and Calculate" Max Tegmark says ,..... it helps to distinguish between two ways of viewing our external physical reality. One is the outside overview of a physicist studying its mathematical structure, like a bird surveying a landscape from high above; the other is the inside view of an observer living in the world described by the structure, like a frog living in the landscape surveyed by the bird." I think there is something missing which is inside but transcending the singular perspective formed from received data. Which is something like (but not quite) the ocean's relationship to its constituents or the "soils" to it's. Not from here or there looking here or there but -as everything is-, everywhere at once, from everywhere without the distortion of data transmission times. That is objective absolute truth which is independent of impoverished individual perspectives based upon a sub sets of information. I strongly believe that truth is absolute and independent of subjective interpretation and a complete model of physical reality requires that component.
In your conclusion you write "... the perfectly valid, scientifically confirmable, mathematical representation of aspects of reality ....." I wonder what you are referring to here. Is it the space time continuum? Or did you have something else in mind or are you being intentionally vague?
Lots of food for thought in your essay. I hope others enjoy reading it as much as I did.
Kind regards Georgina
